7. DRUG INTERACTIONS
7.1 BCRP Substrates
Tafamidis inhibits breast cancer resistant protein (BCRP) in humans [see Clinical Pharmacology (12.3)]. Coadministration of tafamidis and drugs that are BCRP substrates may increase the exposure of substrates of this transporter (e.g., methotrexate, rosuvastatin, imatinib) and the risk of the substrate-related toxicities. Monitor for signs of BCRP substrate-related toxicities and modify dosage of the substrate if appropriate.
